Final answer:
Claudius is deceptive in Act IV of Hamlet.
Step-by-step explanation:
In Act IV of Hamlet, Claudius's interaction with Laertes predominantly suggests that Claudius is manipulative. He shrewdly uses Laertes's grief over his father's death and his sister's madness to steer him against Hamlet. Claudius capitalizes on Laertes's vulnerability and desire for revenge to serve his own ends, which is to eliminate Hamlet as a threat to his throne. This portrayal is far from supportive or caring; instead, it firmly cements Claudius's character as one that is cunning and deceptive. When Claudius meets with Laertes after the death of Polonius, he manipulates Laertes into seeking revenge against Hamlet by suggesting that Hamlet is responsible for his father's death. Claudius uses this deception to further his own agenda and maintain his control over the kingdom.
